I am using EJS in the browser (not on the server).
I have some ejs that I would like to use in multiple pages, so I want to put that in its own file, say table.ejs.
Is there a way I can include it in my HTML such that it is immediately accessible to my javascript after onload?
I was thinking something like:
<script id="table-ejs" type="text/ejs" src="ejs/table.ejs"></script>
then in my javascript:
ejs.render(document.querySelector('#table-ejs').???, data)
Is this possible?
I could use the Fetch API to retrieve the ejs file but then I would need to rewrite a lot of code to make it async. I was wondering if I could avoid that.
Well,
place all your ejs-files within a file "views" - within your views you can create another file "partials" - in this file you place your header and footer.ejs.
Within, lets say, your home.ejs you have to include the following code:
<%- include('partials/header'); -%>
// the rest of your code
<%- include('partials/footer'); -%>

First, here is the Typoscript :
20 = TEXT
20 {
value {
field = field_title
wrap = |.txt
}
filelink {
stdWrap.wrap = <li>|</li>
path = fileadmin/txt-files/
}
}
The result I get is :
<li>
<a href="/fileadmin/txt-files/Title.txt">
<img src="typo3/sysext/frontend/Resources/Public/Icons/FileIcons/txt.png">
</a>
</li>
And what I need is :
<li>
<a href="/fileadmin/force_download_script.php?filepath=/fileadmin/txt-files/Title.txt">
<img src="typo3/sysext/frontend/Resources/Public/Icons/FileIcons/txt.png">
</a>
</li>
I need to make the link downloadable, rather than opening the file in the browser. For that I have a force_download_script.php, but when I do that :
wrap = fileadmin/force_download_script.php?filepath=|txt
instead of the current wrap, filelink doesn't find the file anymore.
I have tried using ATagBeforeWrap.wrap but it doesn't look like it's made for that purpose. I also tried typolinkConfiguration.wrap without any success.
Any idea of how to achieve that ? Using a COA maybe ?
Thank you !
I would not do this with a script, but with server configuration. If you use Apache and have .htaccess enabled, you can add the configuration to a .htaccess file in the directory where the files are located. See https://css-tricks.com/snippets/htaccess/force-files-to-download-not-open-in-browser/
Alternatively you can also use the HTML5 download attribute. This is not supported by Internet Explorer however (it is supported by Edge though).
The issue can get quite a bit complicated, but step by step:
your code above might be wrong if it's not just a copy & paste fault:
wrap = fileadmin/force_download_script.php?filepath=|.txt
The dot before txt was missing.
Nevertheless it is still interesting if the php-script is triggered.
It's possible that the script is not triggered due to some settings in typo3conf/LocalConfiguration.php respectively some settings in the install-tool.
Depending on the TYPO3-Version it's also possible that the script is not triggered at all because all scripts are being required now in an extension. That means you might need to create an extension for that script.
Also simple wrapping of the result with the script-path might not be enough, but you have to call it explicitly by TypoScript perhaps by including the script as user-function or lib.
The admin-panel might be useful to debug some things about your script but if not you've to include some debug-output first in your own code, if that's not enough in the core (temporary).
So you've to find out if your script is triggered and if not, the reason for it.
Are you sure .filelink is what you are looking for?
.filelink is for a set of files. For all files in the folder given by .path a link will be generated. see manual
From your description you want a text wrapped with a link to one single file. That would be more a problem for .typolink where you specify the link in .parameter.
if you really want a link list of multiple files, each wrapped with your script you need to modify .typolinkConfiguration.parameter which will be used internaly by .filelink.
Anyway it might be possible to do a wrap which then would be:
.typolinkConfiguration.parameter.wrap = /fileadmin/force_download_script.php?|
Maybe it is easier to build your list with .stdWrap.filelist, where you can use the filenames in any way to wrap your own href parameter for an A-tag.
To use the TYPO3 core solution with file links you can use this guide:
Create a file storage where you want your "secured" files in TYPO3 backend
Do not set the checkbox "Is public?" in the storage record
The links will be rendered with eID and file parameters
You can look into the FileDumpController handling these links: https://github.com/TYPO3/TYPO3.CMS/blob/2348992f8e3045610636666af096911436fa1c89/typo3/sysext/core/Classes/Controller/FileDumpController.php
You can use the included hook to extend this controller with your logic.
Unfortunately I can't find any official documentation for this feature, but will post it when I find something or wrote it myself. ;)
Maybe this can help you, too: https://extensions.typo3.org/extension/fal_securedownload/
Here is the official part, but it's not much: https://docs.typo3.org/typo3cms/CoreApiReference/ApiOverview/Fal/Administration/Storages.html?highlight=filedumpcontroller
The problem seems to be with EJS. I might be trying to do something EJS wasn't designed for.
I'm working on a web app that uses forms with a variable number of fields. If a Mongo document I'm editing has only one field, I don't want to display input boxes for any additional fields.
I'm able to dynamically control how many fields are displayed when documents are edited but I'm not able to dynamically display the current value of the fields.
If I use the value tag like this: value=<%= document.field1 %>, it works fine. This, however, would have to be manually repeated for each field, including fields that won't be present.
What I want to do is something like this: value=<%= 'document.field' + (i+1) %>. This would ideally produce the same rendered HTML the code above does. However, what I see is 'document.field1' rather than the data I want to retrieve from the database.
EJS is just a thin wrapper around JavaScript code. Anything you can write in JavaScript you can write in EJS, it'll be included in the compiled template without modification.
So to reference a field with a dynamic name you'd use [] just like you would in any other JavaScript code. Based on the code you provided it would be something like this:
value="<%= document['field' + (i + 1)] %>"
I am trying to include an ejs file that contains functions for setting up my views. These functions were defined to be used a helpers. I have tried using:
<% include helpers.ejs %>
But when I try to use the function from this file:
<% module_start('$body', [{name:'display',value:'block'}], 'body'); %>
I get the error:
Reference Error: module_start is not defined
When I copy over the code from 'helpers.ejs' to my original view file, 'test.ejs', it works as expected. I have gone through several answers and,
am still confused what am I doing wrongly in this case.
Thanks for your help in advance.
After some grueling hours of trying every conceived solutions out there, I have landed upon a solution that is working. The solution was borrowed from:
EJS Functions
Looking at the solution presented in this code, I updated my 'helpers.ejs' to 'helpers.js'. Following this, I added the exported functions from 'helpers.js' to the ejs render context object:
const ejs_helpers = require('path/to/helpers.js');
...
ejs.renderFile('filename', { helpers:ejs_helpers, ...}, (err,data)=>{});
In the ejs view file:
<%- helpers.function_name(params); %>
This considerably changes how I initially approached the problem. With plain ejs helper file, the functions include HTML in between the control flow statements. In the case presented here, the functions returns plain string. Notice the '-' with the 'Scriptlet' tag.
Hope this helps someone.
I want to get a list of filenames from a directory in my Docpad project and then pass them to the client for preloading. What is the best way to do this?
What I have been trying is to extract a list of file names from the directory and then pass them to the client via the document.
So I have a collection, like so in docpad.coffee:
collections:
myImages: ->
#getFilesAtPath({relativeOutDirPath: 'images'})
And then in the footer of my html, I've been trying something like this:
<script>
var images = <%= #getCollection('myImages').toJSON() %>
</script>
This however is not coming even close to working. What I really want to do is have images set to an array of urls pointing to the files. But I can't seem to figure out how this would be done. The Docpad documentation and the Query-Engine documentation are simply to sparse.
Anyone have any ideas? Or is there a totally different way to think about this? Is there a way to hand over a variable directly from the Node/Docpad backend to the client, by passing the need to pass it along with the HTML?
Not sure why you want to separate it as a script (btw if you want you can really put it in a separate script if it is called js.eco). I guess it is just for clear separation.
This is how it will work:
<script>
var images = [];
<%for obj in #getCollection("myImages").toJSON(): %>
images.push('<%= obj.url %>');
<% end %>
console.log(images[0]);
</script>
So you will have an array with url's only. I've put there an info to print out in console first element to show it works.
I am using Play and its templating engine to generate web pages. The content of each page is (partially) stored in an SQL database, either as markup text or as plain HTML. Is it possible to include template snippets (without arguments) within this content?
Here is a small example. Let's say that I have some template #printText() and that this template has been imported at the top of the current view. The following content is stored in the database:
<div>
#printText()
</div>
Is it possible to pass this String to the view and render it properly (including the call to #printText())?
You can easily create for an example static method which will fetch snippet from the database by some key and use it in the view like:
<div id="footer_snippet">
#Html(fetchSnippet("footer"))
</div>
It just should find your snippet in the DB and return the markup HTML as a String
